Monitoring Aromatic Organics For Optimizing Coagulation

With the increasing awareness about the negative effects of organics within the water and wastewater treatment process along with increasingly strict water quality regulations, the need for more effective organics removal is becoming more important.

One of the most problematic types of organics is the aromatics. The ring structure of carbon atoms in aromatic molecules causes them to readily attach with various functional groups. This makes highly aromatic organics generally more reactive than other organics. Examples of aromatic organics are humic acids, such as tannins commonly found in surface water sources. Non-aromatic (aliphatic) organics include fulvic acids and other types of less reactive organic molecules.
